Satsuki Satonaka, who has a boyish appearance, is a social butterfly residing in a small town. Ever since childhood, Satsuki has been attached to Takumi Kusuki, who once helped her out in a pinch. One day, while visiting Kusuki, she stumbles upon pornographic magazines in his home. As Satsuki views the erotic acts depicted in the magazines, she develops a desire to reenact them with Kusuki, but he refuses. Feeling that Kusuki does not view her as a proper woman, Satsuki decides to seduce him by tempting him in a lewd manner that even he cannot ignore.
